Abstract

L'invention concerne un récepteur radio multicanal configuré pour une évaluation de canal radio en temps réel. Dans un exemple, un frontal radiofréquence (RF) fournit un spectre de fréquence qui est converti en un spectre numérisé. Dans un sous-système numérique, des ressources (par exemple un logiciel ou un dispositif matériel) peuvent analyser des canaux ou des parties du spectre dans le spectre numérisé pour obtenir un taux d'erreur sur les paquets (PER) à une pluralité de niveaux de puissance et pour une pluralité de techniques de modulation. L'analyse peut donner un indicateur d'intensité de signal reçu (RSSI) requis qui est nécessaire pour entraîner une exigence de fiabilité de lecture (RRR) particulière. A l'aide du RSSI requis, des points d'extrémité communiquant avec le récepteur radio multicanal peuvent être associés à un ou à plusieurs canaux, à une ou à plusieurs techniques de modulation et/ou à un ou à plusieurs niveaux de puissance qui entraînent la RRR. L'analyse peut être effectuée par une ou par plusieurs ressources fonctionnant en parallèle et en arrière-plan d'autres communications entre les points d'extrémité et le récepteur radio multicanal.
